Cooperative description of type cultures of Streptomyces. IV. Species descriptions from the second, third and fourth studies

Abstract

The International Streptomyces Project is a cooperative effort by more than 40 collaborating laboratories representing 18 nations to assemble and redescribe authentic type strains or acceptable neotype strains for species of the genera Streptomyces and Streptoverticillium. Descripktions based upon currently acceptable criteria and methods are published in the International Journal of Systematic Bacteriology. Specimens of the redescribed type strains are deposited in the American Type Culture Collection, the Centraalbureau voor Schimmelcultures, the U. S. S. R. Research Institute for Antibiotics and the Institute for Fermentation, Japan. This report adds descriptions for type strains of 100 additional species to the 200 species previously deposited in the collections and described in Parts II and III of this series.
